Question ABS INOP light came on. Why?

Any ideas on why this happend. I shut the car off & then started it & it stayed off. This is the second time it did this since my Head install.

Thanks

I've had mine come on and stay on a couple of times. Both times one of the upper brake lights in my spoiler were burned out. As soon as I replaced them it went out. I would check that first if you haven't already.

If you have a plug wire to close to the brake line, that will set it off as well.

Well my brake lights all work. I am curious as to why the plug wires will set it off. It may just be coincidence but I am running my wires along side the valve covers which some are close to some brake lines....

Plug wires close to ABS sensor wires, not brake lines can cause an ABS light.
